Abstract
Cl--ATPase activity resides in the basolateral membrane of gut cells. The sugar alcohols sorbitol, mannitol and glycerol could not maintain any cryoprotection of the basolateral membrane fraction for at least 1 2 hr. The sugar, mannose, could not maintain any cryoprotection of bas olateral membrane for at least 12 hr, while sucrose could only maintai n 20% of basolateral membrane Cl--ATPase activity after 12 hr. Trehalo se cryoprotected basolateral membrane Cl--ATPase activity by 98% of co ntrol up to 48 hr.
